Appleation filed June S,

This invention relates to means for hanging pipes, machinery or otherapparatus from ceilings or walls and particularly to an insert, whichisV adapted to bei embedded Vin concrete, plaster or the lilre to anchora supporting member therein.V

1t is my object to provide an insert, adapted to receive and supporthangers of differentliinds andgsizes, whereby the selection of thehanger best suited to conditions prevailing in a particular installationis permitted.

lThe invention will be best understood by reference to the accompanyingdrawings in which Figure 1 is a central, longitudinal section throughthe preferred form of my invention, embedded in concrete and showing abolt in position for insertion; Fig. 2 is a transverse section .throughthe device showing a differentform of hanger therein; Fig. 8 is abottom, plan view of the preferred form of the invention; Fig. 4 is atransverse section through an alternate form of the invention; Fig-5 isa plan view of the preferred lform of nutfor the hanger shown in Fig. 2and Fig. 6 is a section taken on the line 6 6 of Fig. 5.

As shown in Figs. 1 to 3, inclusive, my. de-

y vice consists of a hollow casting 7, which is adapted to be embeddedin a ceiling or wall 8 of concrete, plaster or the like.r The top andsides of the casting 7 are closed and the bottom has an opening 9 intowhich a bolt 10 or pipe hanger 11 may be extended. Unch-iront, outersidewalls on the casting 7 are arranged to positively interlock with thesurrounding concrete. Within the casting7 is a lower chamber 12 and anupper chamber 13. In

the bottom of the chamber 13 and communii eating` with the chamber 12 isan opening 14 of key-hole shape, adapted to receive the head 15 of thebolt 10. Along the lateral edges of this opening 15 is apairof vflanges16, arranged to support the head 15. rllhe opening 9 in thev bottom ofthe chamber 12 registers with the opening 14 and is also of key-holeshape to receive a nut 17 upon the threaded upper end of the hanger 1-1.This nut 17 is preferably formed, as indicated in Figs. 5 and 6, indish-shape with a. tapered bore 18 arranged to receive the threadedupper end of the hanger y e 1t cannot be removed from engagement withINSERT. i

-19,"adapted to facilitate securing the insert upon a concrete form, vashereinafter described..v

In the alternate form of my device shown in Fig. 4,1 provide a hollowcasting 20 in which are formed chambers 21 and 22 for the nut 17 andhead 15 respectively. These chami bers are separated by a wall 223 andhave openings 24 and 25 respectively, similar to the openings 9 and 14of the preferred construction, but upon opposite outer sides ofthecasting. 1t will. be noted that the opening 24 is in one flat side 26 ofthe casting 2O and the opening 25 is in a parallel flat sidev 27. Fairsof ears 28 and 29 are formed respectively in continuation of the sides26 and 27 for securing the casting 2O upon the concrete form, said earsbeing similar to the ears 19 of the preferred construction.

In. the construction of a building, before the concrete 8 is pouredandafter the forms therefor have been constructed, an insert oraplurality of them are secured upon the forms with the openings 9 closedby the forms.

Small nails may be driven between the pairs of ears 19 to'hold thecasting 7 in place. Now when the concrete is poured, it embeds thecasting 7, as indicated in Fig. 1, and extends beneath the undercutsizes thereof to securely hold .it in place. When the concrete has setand the forms therefor are removed, theeinsert 7 is retained in theconcrete and presents the openings` 9 and 14 in the exposed surface ofthe ceiling or wall. llien it isdesired to secure machinery, pipes orother fixtures to the insert by means of a standard bolt,'such as thebolt 1() shown in Fig. 1, vsuch bolt-is inserted, as indicated in Fig.1, in oblique position, so as to pass the head 15 through the enlargedend of the opening 14. When thehead has been inserted above the flanges16, the bolt may be moved to the vertical position, indicated-in dottedlines, in which position the flanges 16. These supporting flanges 16 areof sufficient length to, permitlimited adjustment or movement of thebolt within the insert. rNew by turning a nut upon the threaded, lowerend of the bolt 10, the lixtures may be secured to the ceiling or wall.According to present gpraetiee, -meta'l bands are frequently used toattach machinery and piping to walls or ceilings and the bolt 10may beinserted through p er-'t'orastio.Ils finySllGh apifpe 3() 2)l may ybesuspended'therefrom, instead `Voi, jl`io1ii`tlie bolt To .support thistype of hanger, the nut gli'ris thread-V ed uponv the upper endet themember 11'1 and by vreason of the tapered thread, kmay be turned" down'Vsnugly so aste prevent accidental withdrawal :by subsequent turning of.i the nut in the hanger. Now, bytllting the hanger 11 to one side, thenut 17 maybe insertedfthrough the enlarged end 0i the openy "ing 9 andthe hanger moved to vertical position, as shown 'inf'Fig 2. hanger ring31 having a tapped boss '32 to receive' the lower end ofthel member 11maybe employed to Vsupport the pipe 3Q, or other object to be supported.V"lhie -:pipe 30,with the ringl 31 thereon, vis then elevated andthelower end lof "the hanger v'11Yis finally turned the desired distanceinto vthe threaded bore of Vthe in lFig. el', it is necessaryy todecide,be"fore sethe jbolt 1() are required in the particular lo Cilboss 32l whilel rotating` the nut 17 in the insert 7.

what size or 4kind hanger isfto used in the particular location, namely,whether oil the typeot thebolt'lll or l.larger hangerl. Thus, w ierethehanger 11 is to'be nsed,;the surface 26 ot the casting 20 is placedincon* tact with the concrete ier-mand the ears Q8 are secured to theform. Qther'vviSe, it'bolts like cation, thesurfaces 27 of thecastingsfQO are placed incontaet with the concrete form and the ears 29are-secured tothe lorm. Now

vwhen the Concrete is poured, itisA excluded from the lower chamber 21er22 and allowed Vtojenter the upper one olf said chambers.

` V-VWhen the concrete ornii's removed, either the opening 24 or AtheopeningmQ vis accessible for insertion of the :bolts 1Q or hangers 1,1,as above described. e

As w1 leer' be anderswo@ my mrroid ,.'insert obnij'ates .the necessityfor inserts of diilerentsrzes with erred construction, shown in Figs.,1, 2 and v 3, it is unnecessary to decide in advance el:V theinstallation oi' the insertwhat type' of hanger is to be employed orwhat type ot fixture or piping is to be anchored by meansof the insert..lNhile I have described somewhat in detail the bolts 10 andfhangers 11,itY is to be understood that other types of hangers maybe secured invthe insert and I do not wislrto--li1nit my .invention to any particularhanger.
